inertia

_______ is an object’s tendency to resist acceleration

more 

an object with larger mass will have _____ inertia 

moment of inertia

___________ is an object’s resistance to angular acceleration

• object mass

• distribution of mass with respect to the axis of rotation

moment of inertia is a function of what two things:

radius of gyration

______________ varies with respect to different body axis; figured out for body parts and the bigger the body part, the bigger this is

angular momentum 

___________ is the product of moment of inertia and angular velocity 

angular work

__________ is torque times the change in theta

angular velocity

changing the moment of inertia causes a change in the ______________ to preserve the total momentum
